moon AND CEI ING'PLATE non PIPES.

Application filed April 1. .1926. Serial No. 99,050.

This invention relates to floor or ceiling plates for pipes, that is, such plates as are customarily used, for example, upon'exposed heating pipes in buildings, whele. they pass through the floors andceilings. A" plate of this kind should heath-active in appearance,

easy and cheap to make, and easy to apply,

And when applied it should grip the pipe firmlyand remain securely in position.

The object of my present invention is" to i provide a plate ofithis character, which shall the plateis formed.

ance.

embodyall offthe abm e mentioned requirements to a more marked degree than has been attained by any such 'platesiof whichI am aware. j i r i The manner in which this object is attained willinow he setforth in detail. V

In the drawing Fig. 1 is atop, plan View of my improved plate, as it appearsfwhen in position on apipe; Fig. 2 is a similar-view,

with the parts separated, as'is done, for example, in applyingthe plate to a pipe; Fig. 3

' character with spring means tor-gripping the r is similar to Fig. 2, excepttliat it shoi'vs the bottom instead of the top; and Fig. l shows one of the two'semhcircular halves of which Referring to the drawing, it will be noted that the plate proper consists of two duplicate senii-circular halves l, 2, each provided with a semi-circular opening 3, 4;, on the inside, the outer and innerwedges of each half being preferably rolled as'indicated atR;

in order that they may present a neat appear- Referring nowtothe semi-circularhalf 1, for example, itwill be seen that it is provided with an extension at each end, the-one marked 1 being'a flush,rounded extension, and the one marked 1' being depressed and being provided with a sloping guide edge 1 the purpose of which will be explained more fully in a moment. The semi circular halt 2 is an exactduplicate of 1, the parts 2?}, 2 and 2 corresponding to l, a1 and'l Asappears most clearly from 4, the flush extension 1 is punched and drawn to form an eyelet shank 1 The depressed GX- tensionis punched with a hole 1 of such a size that the eyelet shank 2 of the half 2 will fit within it. Similarly the eyelet shank 1 is adapted to fit into the hole 2 of the half 2.

The assembling of the two halves is a very simple and inexpensive operation. It consists simply in placing the eyelet shank 1 for example, into the hole 2 and then heading over the eyeletshank, with the result that a sturdy hinged joint is formed. The other eyelet shank is not headed but left in its original-form, so that when the two halves are closed up into the position shown in Fig. 1 this other eyelet shank 2 will ride upon the guidel and then spring into the l1ole,1 ,thus holding the two halves securely together. To open them up again it is necessary merely to separate the end 2 laterally from the end 1.

sufiiciently to disengage the eyelet shank 2 from the-hole 1', when the parts I may be swung apart freely about the hinge formed as above described. The depressed extensions 1 and 2 are depressed sulficientlyso that the flush extensions 2 and land the plates 1 and '2 themselves, will lie flush and in the same plane, when the parts are in the position of Fig. 1. p

It is custon'iary to provide plates of this pipe when the plate isin position. My plate as described above may bep'rovidcd with any spring means suitable for this purpose. However, I prefer to use the particular spring devices illustrated at S in. the drawing. As there appears, there is one of these devices in each semi-circular half. Each device consists of a. -V-shaped, or cotter-pin-shaped spring, the head of whichis adapted to be inserted in a small slot in the rolled over inner edge of the semi-circular half, so that the spring ends embrace the pipe when the plate is in position. p l

The particular novelty in these spring devices resides in the cross-sectional form ofthe s aring strips of which they are made. That 13,. as shown in the drawing these strips are along the'pipe-only by the applicationof con-, siderable force- Thus the use of these spring devices upon plates of this character insures their remaining in position.

From the above description it is obvious that the manufacturing operations mvolved in the nmnutacture and assembling o'l my improved plate are extremely simple and inexpensive. In the first place, it is important. to note that the manufacture is simplified by the fact that the two halves are identical, requiring but a single die. And in the second place, 1 wish to stress the ease of assembling, this operation consisting merely in heading one of the eyelet shanks.

In the claims. where the words down or up are used. I am treating the plate as a floor-plate. so that: down means toward the tloor. l have adoptei'l this method of expression a matter of convenience. only, and not by vay of limitation.

The terms and expressitms which I have employed are ised as terms of description and notof limitation. and I have no intention, in the use of such terms and expressions, of excluding any nnj chanical etpiii'alent of the Features shown and described. or portions thereof. but recognize that various modifications are, possible within the scope of the invention claimed.

\Vhat. I claim is:

1. In a lloor and ceilingplat structure for pipes, two identically formed semi-circular members. an extension lug l'ormed integrally with one end of each member. a depressed seat formed in the other end of ca -.h member to closely lit the complementary 'l'ormed extension big. and a hinge connection between the lug of one. member and the depressed seat of the other member. the titted relation ot' the lug and the peat. causing the parts to snap into locked relation when the members are moved to circle closing position. the extension hr; oi each member being provided with an opening and said depressed seat portion ot each member being provided with an eyelet shank whereby the eyelet shank ot one member is adapted to provide a hinge pin and the eyelet ehan k of the other member is adapt ed to provide a latching member for engagement with the opening in the depressed seat of the other member.

S2. A device of the character describetil, comprising a pair of identically termed and interchangeable semi-circular members. iach member having an ot'ienin at one end and a downwardly extending eyelet shank at the other. one of said eyelet shanks being permanently retained in the opening. in the other member by being headed over. thereby securing" these ends oi" the members pivotally together. the other eyelet shank being adapted to tit into the other opening tor detachably holdin;- the other ends of the men'lbers together. the member which has the opening into which the shank is adapted to tit detachably being provided with a guide for guiding said shank into said opening.

I). A device ot' the cha actor described. comprising a pair of identically formed and interchamz ealile sen'ii-circinar members. rat-h member having at one end a tlnsh extension provided with a downwardly ext ndin eye let shank. and at the other with a depre. ion 1)]0Vltl0tl with an o ie'nine', the tlush extension of iach member being adapted to rest in the depression of the other member. with the evelet shank passing through said opening. oinof said eyelet shanks being permanently re tained in the opening by being headed over. thereby securing; those ends of the members pivotally together, the other eyelet shank and its opening serving as a detachable eonnez tion for the other ends 01 the members. the member which has the opening. into which the shank is adapted to lit detachably heme provided with a guide for guiding said shank into said opening.
